Due to a hardware defect, the password for the Firefox account had to be recreated, now all passwords that were saved in the browser are missing. How can I restore the passwords?

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .


Firefox 80+ has a logins-backup.json file in the profile folder that can be used in case of issues with logins.json or to undo an accidental delete of a login, so you can check if you can find this file in the profile folder or in a backup and replace the current logins.json. Make sure to keep a backup copy of all involved files (logins.json and key4.db and logins-backup.json)

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

If you use a Primary Password then you can prevent losing passwords by canceling the PP prompt. You need to logout beforehand by canceling a PP prompt, e.g. by clicking the eye icon in Lockwise (about:logins).

Did you possibly reset the password of the Sync account because you forgot the password? Resetting the password for the Firefox Account will remove all data stored on the Sync server because this password is used to encrypt your data before it is uploaded to the Sync server and only this password can decrypt this data.

You need a backup copy of logins.json and key4.db in the Firefox profile folder to recover lost logins.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

You can check if you have an "Old Firefox Data" folder on the desktop in case the Refresh feature in Firefox has been used and a new profile has been created.
